WEBVTT 00:00.120 --> 00:07.800 In order to solve this error, which is a hilt component issue, we need to create a module because 00:08.040 --> 00:13.840 inside the map view model we provided two parameters and we inject them. 00:13.880 --> 00:16.560 Marker repository and location repository. 00:16.560 --> 00:23.720 In the previous videos we used the Firebase module in order to provide firebase repository and marker 00:23.720 --> 00:24.600 repository. 00:24.840 --> 00:34.120 Now we're going to do in the same way here a new module object named as location module. 00:34.400 --> 00:40.840 And this object provides the location and repository. 00:40.880 --> 00:47.640 Let's start with provides singleton and provide location repository. 00:47.800 --> 00:51.400 It needs application context variable. 00:51.400 --> 01:01.110 And this function returns a location repository instance which is equal to location repository Implementation, 01:01.110 --> 01:08.590 as we said before in the previous videos, provides annotation marks a function as a dependency provider, 01:08.590 --> 01:17.750 Singleton ensures only one instance is created ensured, and this object has two annotations. 01:17.750 --> 01:26.750 The module and installing the module marks this as a hilt module that provides dependencies. 01:26.750 --> 01:37.150 Installing makes, provide or makes provided dependencies live as long as the application, so we had 01:37.270 --> 01:44.750 only one function provide location repository the module structure object location module. 01:44.790 --> 01:53.350 A Kotlin singleton that groups related dependencies contains one or more provides a function, but in 01:53.350 --> 02:00.990 this case we have only one function providing the location permission and location repository The parameter 02:00.990 --> 02:09.510 application context injects the application context avoids memory leaks and location repository interface. 02:09.550 --> 02:10.750 Abstract type. 02:10.950 --> 02:19.310 The implementation returns a concrete location repository implementation passing context as a parameter. 02:19.430 --> 02:21.030 Why this pattern? 02:21.070 --> 02:24.430 Decoupling implementation from usage. 02:24.590 --> 02:30.110 Making testing easier and centralizing dependency creation. 02:30.150 --> 02:33.750 The hilt specific advantages used for or. 02:34.230 --> 02:35.590 The advantages are. 02:35.630 --> 02:40.030 Auto generates dependency injection code at compile time. 02:40.230 --> 02:49.510 Manages component lifecycles automatically reducing boilerplate code compared to manual dependency injection 02:49.510 --> 02:51.070 and the singleton scoop. 02:51.110 --> 02:59.390 Location services typically need app wide access, avoiding recreating expensive resources. 02:59.420 --> 03:02.220 This is the idea behind creating a model. 03:02.380 --> 03:06.940 Let's build our application and run it. 03:06.940 --> 03:07.780 And here we go. 03:07.820 --> 03:09.020 This is our map. 03:09.180 --> 03:14.100 Let me move to here United States and uh, let me. 03:14.140 --> 03:20.500 And the location didn't appear because I set it to San Francisco. 03:20.500 --> 03:24.260 So you can set and change the current location from here. 03:24.380 --> 03:28.020 From the extended controls, go to location. 03:28.020 --> 03:31.580 And here you can set it on the map. 03:31.580 --> 03:33.140 You can set it here. 03:33.380 --> 03:42.460 And for example in Las Vegas save point click okay and click on Set location. 03:42.460 --> 03:46.700 You can notice that Las Vegas is set as our location. 03:46.740 --> 03:48.900 Now we have an error. 03:48.940 --> 03:52.220 We are not uh requiring the permissions. 03:52.220 --> 04:03.690 And here open the manifest uses permission course access find location and uses permission course location. 04:03.730 --> 04:04.330 Okay. 04:04.370 --> 04:07.290 Also you can use access background location. 04:07.410 --> 04:11.450 Let's run our application again and congratulations guys. 04:11.730 --> 04:16.730 Our application is requesting the permissions during the runtime. 04:16.730 --> 04:20.370 Only this time don't allow or while using the app, click. 04:20.370 --> 04:25.770 While using the app, go to here and wait for the location to appear. 04:25.890 --> 04:31.410 If the location didn't appear, you can go to the settings, so click here. 04:31.530 --> 04:37.650 Go to settings search for location use location is enabled. 04:37.650 --> 04:39.770 See all permissions. 04:39.810 --> 04:43.090 Application allowed only one. 04:43.130 --> 04:50.410 Use the Uber clone the location services location accuracy is on. 04:50.570 --> 04:57.490 Okay, the last thing we need to check is the internet permission access, file location, access course 04:57.530 --> 05:02.610 location and also the metadata API key is set it correctly. 05:02.730 --> 05:07.690 Now let's run our application and see the current position. 05:07.730 --> 05:09.250 These are the markers. 05:09.370 --> 05:11.210 And here we go. 05:11.250 --> 05:13.890 This is our current location. 05:13.890 --> 05:20.010 If you need to change it go to this three dots icon. 05:20.010 --> 05:24.850 And you can for example like change it to Brazil. 05:25.170 --> 05:30.090 Set location and wait for the current location to be changed. 05:30.130 --> 05:31.490 And here we go guys. 05:31.490 --> 05:36.330 After maximum 10s it will appear in the new location. 05:36.530 --> 05:45.930 This is due to the location updates and we set the interval to ten milliseconds 10,000 milliseconds. 05:46.170 --> 05:47.810 Okay thank you guys. 05:48.010 --> 05:53.410 This is how we fetch the location updates in Google Maps.
